Find solution of circuit in the attachment
Find the value of x

If R=5ohms​

Answer 1

Given:-

• R1=6ohms
• R2=x
• R3=2ohms
• Equivalent resistance=R=5ohms

To find:-

Value of x

Solution:-

• All resistances are connected in parallel.

$\boxed{\sf \dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+\dfrac{1}{R_3}}$

$\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{1}{6}+\dfrac{1}{2}+\dfrac{1}{x}$

$\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{1+3}{6}+\dfrac{1}{x}$

$\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{4}{6}+\dfrac{1}{x}$

$\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{2}{3}+\dfrac{1}{x}$

$\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{2+3}{3x}$

$\\ \sf\longmapsto \dfrac{1}{5}=\dfrac{5}{x}$

• Use Cross multiplication

$\\ \sf\longmapsto 3x=5\times 5$

$\\ \sf\longmapsto 3x=25$

$\\ \sf\longmapsto x=\dfrac{25}{3}$

$\\ \sf\longmapsto x=8.3$
